Problems solved by technology

[0003] Nevertheless, the mainstream PVC antenna cover on the market will undergo large deformation after high and low temperature shocks, and because the linear expansion coefficient of the antenna cover and the reflector is greatly different, it will cause the end cover of the antenna cover to separate from the antenna cover. Problems such as poor waterproofing
Moreover, the existing PVC antenna cover can only be applied in the scene where the temperature is -40°C~70°C, which cannot meet the requirements of all-weather applications
The manufacturing cost of the existing PVC antenna cover is also relatively high. In order to improve the heat resistance of the antenna cover, a large amount of heat-resistant modified resin ABS has been added, resulting in high manufacturing costs, and the addition of ABS will also lead to a decrease in the UV resistance of the antenna cover. reduce
In addition, the prior art does not provide a solution to the thermo-oxidative aging effect affecting the PVC antenna cover

In addition, the invention also provides the preparing method of the heat-resisting material. The heat-resisting material can be used for the preparation process of base station antenna outer covers.

Description

technical field [0001] The invention relates to the field of materials, in particular to a high-temperature-resistant material, a preparation method thereof, and a base station antenna cover. Background technique [0002] Communication base station antennas are generally installed at high altitudes, such as iron towers or roofs. The installed base station antenna is in a harsh outdoor environment for a long time. Therefore, the antenna cover material needs to have the characteristics or performance of high and low temperature impact resistance and UV (ultraviolet, ultraviolet) radiation resistance to meet its long-term and reliable outdoor application. PVC (polyvinyl chloride, polyvinyl chloride) material has the characteristics of low dielectric, corrosion resistance, cold resistance, UV resistance and self-flammability. Compared with the traditional antenna cover material FRP, it also has light specific gravity, low cost and good formability. , Recyclable and other advant...
